Hive mind?
Allomere just slew one of his marshals in public. Various members of the government have had trouble with several lords and a duke, for differing reasons. Not to mention the contesting on who gets to be Judge and Banker and where food can be sold. I don't really feel obliged to comment further on inner realm happenings but the reputation so many seem to think we have is quite flattering. Life would be a lot easier if we were all jolly and cohesive IC. The difference is we all seem to otherwise enjoy the internal dynamics with little animosity.
There's probably also a bit of fortress mentality to it too.
